Overall goals of this exploratory pilot study are to study the potential efficacy of a diabetes prevention education program that includes training in mindfulness-based stress reduction for pre-diabetic African Americans. Specific Aims are 1) to determine the feasibility of developing a clinical trial to compare the effectiveness of a mindfulness-based diabetes prevention program (treatment group) with a conventional diabetes prevention program (control group) in improving glucose metabolism in pre-diabetic African American adults; 2) to identify relevant physiological and psychological secondary outcomes associated with a mindfulness-based, educational self-care program in African-Americans with pre-diabetes; 3) to assess the acceptability and cultural relevance of MBSR for pre-diabetic African Americans via a post-intervention qualitative study, to include interviews of participants, dropouts, and instructors; and 4) to identify, and find solutions for, problems in conducting a well-powered clinical trial to assess the efficacy of a mindfulness-based diabetes prevention program in improving glucose metabolism in pre-diabetic African-Americans.
